Numerical and Experimental Study of the Performance Effects of Varying Vaneless Space and Vane Solidity in Radial Inflow Turbine Stators.

An extensive experimental program has been carried out on a 135?mm tip diameter radial turbine using a variety of stator designs, in order to facilitate direct performance comparisons of varying stator vane solidity and the effect of varying the vaneless space. A baseline vaned stator was designed using commercial blade design software, having 15 vanes and a vane trailing edge to rotor leading edge radius ratio (Rte/rle) of 1.13. Two additional series of stator vanes were designed and manufactured; one series having varying vane numbers of 12, 18, 24, and 30, and a further series with Rte/rle ratios of 1.05, 1.175, 1.20, and 1.25. As part of the design process a series of CFD simulations were carried out in order to guide design iterations towards achieving a matched flow capacity for each stator. In this way the variations in the measured stage efficiency could be attributed to the stator passages only, thus allowing direct comparisons to be made. Interstage measurements were taken to capture the static pressure distribution at the rotor inlet and these measurements were then used to validate subsequent numerical models. The overall losses for different stators have been quantified and the variations in the measured and computed efficiency were used to recommend optimum values of vane solidity and Rte/rle.

Evaluating the impact of network density, hidden nodes and capture effect for throughput guarantee in multi-hop wireless networks

To optimize the performance of wireless networks, one needs to consider the impact of key factors such as interference from hidden nodes, the capture effect, the network density and network conditions (saturated versus non-saturated). In this research, our goal is to quantify the impact of these factors and to propose effective mechanisms and algorithms for throughput guarantees in multi-hop wireless networks. For this purpose, we have developed a model that takes into account all these key factors, based on which an admission control algorithm and an end-to-end available bandwidth estimation algorithm are proposed. Given the necessary network information and traffic demands as inputs, these algorithms are able to provide predictive control via an iterative approach. Evaluations using analytical comparison with simulations as well as existing research show that the proposed model and algorithms are accurate and effective.

The effect of sub-optimal control and the spectral wave climate on the performance of wave energy converter arrays

A linear hydrodynamic model is used to assess the sensitivity of the performance of a wave energy converter (WEC) array to control parameters. It is found that WEC arrays have a much smaller tolerance to imprecision of the control parameters than isolated WECs and that the increase in power capture of WEC arrays is only achieved with larger amplitudes of motion of the individual WECs. The WEC array radiation pattern is found to provide useful insight into the array hydrodynamics. The linear hydrodynamic model is used, together with the wave climate at the European Marine Energy Centre (EMEC), to assess the maximum annual average power capture of a WEC array. It is found that the maximum annual average power capture is significantly reduced compared to the maximum power capture for regular waves and that the optimum array configuration is also significantly modified. It is concluded that the optimum configuration of a WEC array will be as much influenced by factors such as mooring layout, device access and power smoothing as it is by the theoretical optimum hydrodynamic configuration. © 2009 Elsevier Ltd.

The effect of the spectral distribution of wave energy on the performance of a bottom hinged flap type wave energy converter

The power output from a wave energy converter is typically predicted using experimental and/or numerical modelling techniques. In order to yield meaningful results the relevant characteristics of the device, together with those of the wave climate must be modelled with sufficient accuracy.

The wave climate is commonly described using a scatter table of sea states defined according to parameters related to wave height and period. These sea states are traditionally modelled with the spectral distribution of energy defined according to some empirical formulation. Since the response of most wave energy converters vary at different frequencies of excitation, their performance in a particular sea state may be expected to depend on the choice of spectral shape employed rather than simply the spectral parameters. Estimates of energy production may therefore be affected if the spectral distribution of wave energy at the deployment site is not well modelled. Furthermore, validation of the model may be affected by differences between the observed full scale spectral energy distribution and the spectrum used to model it.

This paper investigates the sensitivity of the performance of a bottom hinged flap type wave energy converter to the spectral energy distribution of the incident waves. This is investigated experimentally using a 1:20 scale model of Aquamarine Power’s Oyster wave energy converter, a bottom hinged flap type device situated at the European Marine Energy Centre (EMEC) in approximately 13m water depth. The performance of the model is tested in sea states defined according to the same wave height and period parameters but adhering to different spectral energy distributions.

The results of these tests show that power capture is reduced with increasing spectral bandwidth. This result is explored with consideration of the spectral response of the device in irregular wave conditions. The implications of this result are discussed in the context of validation of the model against particular prototype data sets and estimation of annual energy production.

Web adoption by Irish credit unions: Performance implications

The purpose of this paper is to examine website adoption and its resultant effects on credit union performance in Ireland over the period 2002 to 2010. While there has been a steady increase in web adoption over the period a sizeable proportion (53%) of credit unions did not have a web-based facility in 2010. To gauge web functionality the researchers accessed all websites in 2010/2011 and it transpired that most sites were classified as informational with limited transactional options. Panel data techniques are then used to capture the dynamic nature of website diffusion and to investigate the effect of website adoption on cost and performance. The empirical analysis reveals that credit unions that have web-based functionality have a reduced spread between the loan and pay-out rate with this primarily caused by reduced loan rates. This reduced spread, although small, is found to both persist and increase over time.

Development of a Bridge Weigh-in-Motion Sensor: Performance comparison using fibre optic and electric resistance strain sensor systems

This paper addresses the problems of effective in situ measurement of the real-time strain for bridge weigh in motion in reinforced concrete bridge structures through the use of optical fiber sensor systems. By undertaking a series of tests, coupled with dynamic loading, the performance of fiber Bragg grating-based sensor systems with various amplification techniques were investigated. In recent years, structural health monitoring (SHM) systems have been developed to monitor bridge deterioration, to assess load levels and hence extend bridge life and safety. Conventional SHM systems, based on measuring strain, can be used to improve knowledge of the bridge's capacity to resist loads but generally give no information on the causes of any increase in stresses. Therefore, it is necessary to find accurate sensors capable of capturing peak strains under dynamic load and suitable methods for attaching these strain sensors to existing and new bridge structures. Additionally, it is important to ensure accurate strain transfer between concrete and steel, adhesives layer, and strain sensor. The results show the benefits in the use of optical fiber networks under these circumstances and their ability to deliver data when conventional sensors cannot capture accurate strains and/or peak strains.

How Video Lecture Capture affects Student Engagement in a University Computer Programming Course: Attendance, Video Viewing Behaviours and Student Attitudes

Introduction
The use of video capture of lectures in Higher Education is not a recent occurrence with web based learning technologies including digital recording of live lectures becoming increasing commonly offered by universities throughout the world (Holliman and Scanlon, 2004). However in the past decade the increase in technical infrastructural provision including the availability of high speed broadband has increased the potential and use of videoed lecture capture. This had led to a variety of lecture capture formats including pod casting, live streaming or delayed broadcasting of whole or part of lectures.
Additionally in the past five years there has been a significant increase in the popularity of online learning, specifically via Massive Open Online Courses (MOOCs) (Vardi, 2014). One of the key aspects of MOOCs is the simulated recording of lecture like activities. There has been and continues to be much debate on the consequences of the popularity of MOOCs, especially in relation to its potential uses within established University programmes.
There have been a number of studies dedicated to the effects of videoing lectures.
The clustered areas of research in video lecture capture have the following main themes:
• Staff perceptions including attendance, performance of students and staff workload
• Reinforcement versus replacement of lectures
• Improved flexibility of learning
• Facilitating engaging and effective learning experiences
• Student usage, perception and satisfaction
• Facilitating students learning at their own pace
Most of the body of the research has concentrated on student and faculty perceptions, including academic achievement, student attendance and engagement (Johnston et al, 2012).
Generally the research has been positive in review of the benefits of lecture capture for both students and faculty. This perception coupled with technical infrastructure improvements and student demand may well mean that the use of video lecture capture will continue to increase in frequency in the next number of years in tertiary education. However there is a relatively limited amount of research in the effects of lecture capture specifically in the area of computer programming with Watkins 2007 being one of few studies . Video delivery of programming solutions is particularly useful for enabling a lecturer to illustrate the complex decision making processes and iterative nature of the actual code development process (Watkins et al 2007). As such research in this area would appear to be particularly appropriate to help inform debate and future decisions made by policy makers.
Research questions and objectives
The purpose of the research was to investigate how a series of lecture captures (in which the audio of lectures and video of on-screen projected content were recorded) impacted on the delivery and learning of a programme of study in an MSc Software Development course in Queen’s University, Belfast, Northern Ireland. The MSc is conversion programme, intended to take graduates from non-computing primary degrees and upskill them in this area. The research specifically targeted the Java programming module within the course. It also analyses and reports on the empirical data from attendances and various video viewing statistics. In addition, qualitative data was collected from staff and student feedback to help contextualise the quantitative results.
Methodology, Methods and Research Instruments Used
The study was conducted with a cohort of 85 post graduate students taking a compulsory module in Java programming in the first semester of a one year MSc in Software Development. A pre-course survey of students found that 58% preferred to have available videos of “key moments” of lectures rather than whole lectures. A large scale study carried out by Guo concluded that “shorter videos are much more engaging” (Guo 2013). Of concern was the potential for low audience retention for videos of whole lectures.
The lecturers recorded snippets of the lecture directly before or after the actual physical delivery of the lecture, in a quiet environment and then upload the video directly to a closed YouTube channel. These snippets generally concentrated on significant parts of the theory followed by theory related coding demonstration activities and were faithful in replication of the face to face lecture. Generally each lecture was supported by two to three videos of durations ranging from 20 – 30 minutes.
Attendance
The MSc programme has several attendance based modules of which Java Programming was one element. In order to assess the consequence on attendance for the Programming module a control was established. The control used was a Database module which is taken by the same students and runs in the same semester.
Access engagement
The videos were hosted on a closed YouTube channel made available only to the students in the class. The channel had enabled analytics which reported on the following areas for all and for each individual video; views (hits), audience retention, viewing devices / operating systems used and minutes watched.
Student attitudes
Three surveys were taken in regard to investigating student attitudes towards the videoing of lectures. The first was before the start of the programming module, then at the mid-point and subsequently after the programme was complete.
The questions in the first survey were targeted at eliciting student attitudes towards lecture capture before they had experienced it in the programme. The midpoint survey gathered data in relation to how the students were individually using the system up to that point. This included feedback on how many videos an individual had watched, viewing duration, primary reasons for watching and the result on attendance, in addition to probing for comments or suggestions. The final survey on course completion contained questions similar to the midpoint survey but in summative view of the whole video programme.
Conclusions and Outcomes
The study confirmed findings of other such investigations illustrating that there is little or no effect on attendance at lectures. The use of the videos appears to help promote continual learning but they are particularly accessed by students at assessment periods. Students respond positively to the ability to access lectures digitally, as a means of reinforcing learning experiences rather than replacing them. Feedback from students was overwhelmingly positive indicating that the videos benefited their learning. Also there are significant benefits to part recording of lectures rather than recording whole lectures. The behaviour viewing trends analytics suggest that despite the increase in the popularity of online learning via MOOCs and the promotion of video learning on mobile devices in fact in this study the vast majority of students accessed the online videos at home on laptops or desktops However, in part, this is likely due to the nature of the taught subject, that being programming.
The research involved prerecording the lecture in smaller timed units and then uploading for distribution to counteract existing quality issues with recording entire live lectures. However the advancement and consequential improvement in quality of in situ lecture capture equipment may well help negate the need to record elsewhere. The research has also highlighted an area of potentially very significant use for performance analysis and improvement that could have major implications for the quality of teaching. A study of the analytics of the viewings of the videos could well provide a quick response formative feedback mechanism for the lecturer. If a videoed lecture either recorded live or later is a true reflection of the face to face lecture an analysis of the viewing patterns for the video may well reveal trends that correspond with the live delivery.

Video Lecture Capture : Student Engagement

Video Capture of university lectures enables learners to be more flexible in their learning behaviour, for instance choosing to attend lectures in person or watch later. However attendance at lectures has been linked to academic success and is of concern for faculty staff contemplating the introduction of Video Lecture Capture. This research study was devised to assess the impact on learning of recording lectures in computer programming courses. The study also considered behavioural trends and attitudes of the students watching recorded lectures, such as when, where, frequency, duration and viewing devices used. The findings suggest there is no detrimental effect on attendance at lectures with video materials being used to support continual and reinforced learning with most access occurring at assessment periods. The analysis of the viewing behaviours provides a rich and accessible data source that could be potentially leveraged to improve lecture quality and enhance lecturer and learning performance.

Teaching Programming - Understanding Lecture Capture YouTube Analytics

ABSTRACT
The proliferation in the use of video lecture capture in universities worldwide presents an opportunity to analyse video watching patterns in an attempt to quantify and qualify how students engage and learn with the videos. It also presents an opportunity to investigate if there are similar student learning patterns during the equivalent physical lecture. The goal of this action based research project was to capture and quantitatively analyse the viewing behaviours and patterns of a series of video lecture captures across several university Java programming modules. It sought to study if a quantitative analysis of viewing behaviours of Lecture Capture videos coupled with a qualitative evaluation from the students and lecturers could be correlated to provide generalised patterns that could then be used to understand the learning experience of students during videos and potentially face to face lectures and, thereby, present opportunities to reflectively enhance lecturer performance and the students’ overall learning experience. The report establishes a baseline understanding of the analytics of videos of several commonly used pedagogical teaching methods used in the delivery of programming courses. It reflects on possible concurrences within live lecture delivery with the potential to inform and improve lecturing performance.

Techno-Economic Feasibility of Selective CO2 Capture Processes from Biogas Streams using Ionic Liquids as Physical Absorbents

Biogas from anaerobic digestion of sewage sludge is a renewable resource with high energy content, which is formed mainly of CH4 (40-75 vol.%) and CO2 (15-60 vol.%) Other components such as water (H2O, 5-10 vol.%) and trace amounts of hydrogen sulfide and siloxanes can also be present. A CH4-rich stream can be produced by removing the CO2 and other impurities so that the upgraded bio-methane can be injected into the natural gas grid or used as a vehicle fuel. The main objective of this paper is to develop a new modeling methodology to assess the technical and economic performance of biogas upgrading processes using ionic liquids which physically absorb CO2. Three different ionic liquids, namely the 1-ethyl-3-methylimidazolium bis[(trifluoromethyl)sulfonyl]imide, 1-hexyl-3-methylimidazoliumbis[(trifluoromethyl)sulfonyl]imide and trihexyl(tetradecyl)phosphonium bis[(trifluoromethyl)sulfonyl]imide, are considered for CO2 capture in a pressure-swing regenerative absorption process. The simulation software Aspen Plus and Aspen Process Economic Analyzer is used to account for mass and energy balances as well as equipment cost. In all cases, the biogas upgrading plant consists of a multistage compressor for biogas compression, a packed absorption column for CO2 absorption, a flash evaporator for solvent regeneration, a centrifugal pump for solvent recirculation, a pre-absorber solvent cooler and a gas turbine for electricity recovery. The evaluated processes are compared in terms of energy efficiency, capital investment and bio-methane production costs. The overall plant efficiency ranges from 71-86 % whereas the bio-methane production cost ranges from £6.26-7.76 per GJ (LHV). A sensitivity analysis is also performed to determine how several technical and economic parameters affect the bio-methane production costs. The results of this study show that the simulation methodology developed can predict plant efficiencies and production costs of large scale CO2 capture processes using ionic liquids without having to rely on gas solubility experimental data.

O gesto na performance em percussão - uma abordagem sensorial e performativa

O presente trabalho discute o gesto na performance em percussão e sua influência sobre as sensações de continuidade, suspensão e conclusão de um trecho musical. Conceitos de gesto utilizados em música e dança foram observados e redimensionados para a execução instrumental percussiva. Três abordagens distintas sobre o gesto na performance percussiva (Gesto Percussivo, Gesto Percussivo Interpretativo e Gesto Percussivo Expressivo) foram realizadas com a intenção de se gerarem mecanismos e ferramentas técnicas, interpretativas e expressivas para o fazer musical do intérprete percussionista. Através de um experimento que teve como objetivo captar sensações de continuidade, suspensão e conclusão de um indivíduo sobre uma performance musical percussiva, foi possível constatar como o movimento corporal age de forma influente sobre as informações musicais passadas pelo intérprete ao espectador.

Educator Evaluation of Academic and Social Competence in Students with Acquired Brain Injury (ABI) Relative to Assessed Performance and Sense of Belonging

Acquired brain injury (ABI) is the leading cause of death and disability amongst children and adolescents andpresents itself with challenges associated in cognitive, social, emotional, and behavioural domains. These changes may interfere with academic performance and social inclusion, influencing self-esteem and personal success. The current study examined a subset of data to capture the sense of academic and social belonging for students with ABI as a function of the classroom teachers’ subjective perception of ability, their ABI knowledge, and student identification. Overall, a discrepancy was found between educators’ subjective ratings of student performance and students’ neurocognitive capacity. Educator knowledge and identification of ABI influenced student success in academic and social domains independent of teaching approach. This research has implications for the identification of ABI in the classroom and related challenges students experience. Educators are underprepared for the reintegration of students returning to school and lack appropriate knowledge and strategies to accommodate individual needs.

Influence du financement sur la performance des systèmes de soins

La thèse a pour objectif d’étudier l’influence du financement des soins de santé sur la performance des systèmes de soins compte tenu des caractéristiques organisationnelles sanitaires des systèmes. Elle s’articule autour des trois objectifs suivants : 1) caractériser le financement des soins de santé à travers les différents modèles émergeant des pays à revenu élevé ; 2) apprécier la performance des systèmes de soins en établissant les divers profils apparaissant dans ces mêmes pays ; 3) examiner le lien entre le financement et la performance en tenant compte du pouvoir modérateur du contexte organisationnel des soins. Inspirée du processus de circulation de l’argent dans le système de soins, l’approche a d’abord consisté à classer les pays étudiés – par une analyse configurationnelle opérationnalisée par les analyses de correspondance multiples (ACM) et de classification hiérarchique ascendante (CHA) – dans des modèles types, chacun représentant une configuration particulière de processus de financement des soins de santé (article 1). Appliquée aux données recueillies auprès des 27 pays de l’OCDE à revenu élevé via les rapports Health Care in Transition des systèmes de santé des pays produits par le bureau Européen de l’OMS, la banque de données Eco-Santé OCDE 2007 et les statistiques de l’OMS 2008, les analyses ont révélé cinq modèles de financement. Ils se distinguent selon les fonctions de collecte de l’argent dans le système (prélèvement), de mise en commun de l’argent collecté (stockage), de la répartition de l’argent collecté et stocké (allocation) et du processus de paiement des professionnels et des établissements de santé (paiement). Les modèles ainsi développés, qui vont au-delà du processus unique de collecte de l’argent, donnent un portrait plus complet du processus de financement des soins de santé. Ils permettent ainsi une compréhension de la cohérence interne existant entre les fonctions du financement lors d’un éventuel changement de mode de financement dans un pays. Dans un deuxième temps, nous appuyant sur une conception multidimensionnelle de la performance des systèmes, nous avons classé les pays : premièrement, selon leur niveau en termes de ressources mobilisées, de services produits et de résultats de santé atteints (définissant la performance absolue) ; deuxièmement, selon les efforts qu’ils fournissent pour atteindre un niveau élevé de résultats de santé proportionnellement aux ressources mobilisées et aux services produits en termes d’efficience, d’efficacité et de productivité (définissant ainsi la performance relative) ; et troisièmement, selon les profils types de performance globale émergeant en tenant compte simultanément des niveaux de performance absolue et relative (article 2). Les analyses effectuées sur les données collectées auprès des mêmes 27 pays précédents ont dégagé quatre profils de performance qui se différencient selon leur niveau de performance multidimensionnelle et globale. Les résultats ainsi obtenus permettent d’effectuer une comparaison entre les niveaux globaux de performance des systèmes de soins. Pour terminer, afin de répondre à la question de savoir quel mode – ou quels modes – de financement générerait de meilleurs résultats de performance, et ce, dans quel contexte organisationnel de soins, une analyse plus fine des relations entre le financement et la performance (tous définis comme précédemment) compte tenu des caractéristiques organisationnelles sanitaires a été réalisée (article 3). Les résultats montrent qu’il n’existe presque aucune relation directe entre le financement et la performance. Toutefois, lorsque le financement interagit avec le contexte organisationnel sanitaire pour appréhender le niveau de performance des systèmes, des relations pertinentes et révélatrices apparaissent. Ainsi, certains modes de financement semblent plus attrayants que d’autres en termes de performance dans des contextes organisationnels sanitaires différents. Les résultats permettent ainsi à tous les acteurs du système de comprendre qu’il n’existe qu’une influence indirecte du financement de la santé sur la performance des systèmes de soins due à l’interaction du financement avec le contexte organisationnel sanitaire. L’une des originalités de cette thèse tient au fait que très peu de travaux ont tenté d’opérationnaliser de façon multidimensionnelle les concepts de financement et de performance avant d’analyser les associations susceptibles d’exister entre eux. En outre, alors que la pertinence de la prise en compte des caractéristiques du contexte organisationnel dans la mise en place des réformes des systèmes de soins est au coeur des préoccupations, ce travail est l’un des premiers à analyser l’influence de l’interaction entre le financement et le contexte organisationnel sanitaire sur la performance des systèmes de soins.

Les dimensions négligées de l'évaluation de la performance : les valeurs et la qualité de vie au travail

L’objet de cette thèse est l’élaboration d’un modèle logique de mesure du maintien des valeurs, ainsi que son opérationnalisation afin d’entreprendre l’évaluation de la performance des systèmes de santé. Le maintien des valeurs est l’une des quatre fonctions de la théorie de l’action sociale de T.Parsons permettant d’analyser les systèmes d’action. Les autres fonctions sont l’adaptation, la production et l’atteinte des buts. Cette théorie est la base du modèle EGIPSS (évaluation globale et intégrée de la performance des systèmes de santé), dans lequel cette thèse s’insère. La fonction étudiée correspond, dans l’oeuvre de T.Parsons, au sous-système culturel. Elle renvoie à l’intangible, soit à l’univers symbolique par lequel l’action prend son sens et les fonctions du système s’articulent. Le modèle logique de mesure du maintien des valeurs est structuré autour de deux concepts principaux, les valeurs individuelles et organisationnelles et la qualité de vie au travail. À travers les valeurs individuelles et organisationnelles, nous mesurons la hiérarchie et l’intensité des valeurs, ainsi que le niveau de concordance interindividuelle et le degré de congruence entre les valeurs individuelles et organisationnelles. La qualité de vie au travail est composée de plusieurs concepts permettant d’analyser et d’évaluer l’environnement de travail, le climat organisationnel, la satisfaction au travail, les réactions comportementales et l’état de santé des employés. La mesure de ces différents aspects a donné lieu à la conception de trois questionnaires et de trente indicateurs. Ma thèse présente, donc, chacun des concepts sélectionnés et leurs articulations, ainsi que les outils de mesure qui ont été construits afin d’évaluer la dimension du maintien des valeurs. Enfin, nous exposons un exemple d’opérationnalisation de ce modèle de mesure appliqué à deux hôpitaux dans la province du Mato Grosso du Sud au Brésil. Cette thèse se conclut par une réflexion sur l’utilisation de l’évaluation comme outil de gestion soutenant l’amélioration de la performance et l’imputabilité. Ce projet comportait un double enjeu. Tout d’abord, la conceptualisation de la dimension du maintien des valeurs à partir d’une littérature abondante, mais manquant d’intégration théorique, puis la création d’outils de mesure permettant de saisir autant les aspects objectifs que subjectifs des valeurs et de la qualité de vie au travail. En effet, on trouve dans la littérature de nombreuses disciplines et de multiples courants théoriques tels que la psychologie industrielle et organisationnelle, la sociologie, les sciences infirmières, les théories sur le comportement organisationnel, la théorie des organisations, qui ont conçu des modèles pour analyser et comprendre les perceptions, les attitudes et les comportements humains dans les organisations. Ainsi, l’intérêt scientifique de ce projet découle de la création d’un modèle dynamique et intégrateur offrant une synthèse des différents champs théoriques abordant la question de l’interaction entre les perceptions individuelles et collectives au travail, les conditions objectives de travail et leurs influences sur les attitudes et les comportements au travail. D’autre part, ce projet revêt un intérêt opérationnel puisqu’il vise à fournir aux décideurs du système de santé des connaissances et données concernant un aspect de la performance fortement négligé par la plupart des modèles internationaux d’évaluation de la performance.

Women Industrial Cooperatives- An Analysis of Its Structure, Performance and Growth in Kannur District

In the present study made an attempt to analyse the structure, performance and growth of women industrial cooperatives in kannur district, Kerala. The study encompasses all women industrial cooperatives registered at the district industries center, kannur and that currently exist. The women industrial cooperatives are classified into two ie; group with network and another group without network. In Kannur there are 54 units working as women industrial cooperatives. One of the main problems the women cooperatives face is the lack of working capital followed marketing problem. The competition between cooperatives and private traders is very high. The variables examined to analyse the performance of women industrial cooperatives in Kannur showed that there exists inter unit differences in almost all the variables. The financial structure structure shows that the short term liquidity of women cooperatives in Kannur favour more the units which have political networks; but the long term financial coverage is seen to be highly geared in this group, not because of a decline is net worth but due to highly proportionate increase in financial liabilities in the form of borrowings. The encouragement given by the government through financial stake and other incentives has been the major factor in the formation and growth of women cooperatives. As a result both productivity and efficiency improves in the cooperatives. In short the present study helped to capture the impact, role and dynamics of networking in general and socio political network in particular in relation to intra and inter unit differences on the structure, growth and performance of women industrial cooperatives societies in Kannur district
